Rein Therapeuticsshares rose 2.5% to $1.24 premarket after the company announced that European regulators granted orphan drug status to its experimental therapy, LTI-03, for idiopathic pulmonary fibrosis (IPF). This condition causes severe lung damage. Early preclinical data indicated improved survival and lung function. LTI-03, a synthetic peptide, aims to protect lung cells and inhibit scarring signals. The drug also has U.S. orphan status, and further trials are planned in multiple countries. However, the stock has declined approximately 50% over the past year.
